To @ZZ whom t may concern.'

Be it known that I, PAUL l. Moriani., a

' citizen of the United States, residing in the -city of New York, county and State oit' hl ew ,.L'Lence oi suitable drying conditions or drying medium.

The object of my invention is to provide an improved apparatusor carrying out the process above mentioned, which apparatus is simple in construction, compact in arrangement, and easy of operation, and is adapted to produce the best results with a minimum waste of the solvent, drying medium or heat. In the disclosure of this form of the invention, 1 do not wish to be understood as being limited to the precise details and arrangement of parts, since this invention is intended to illustrate the typeot apparatus in which variations may be made without departing from the general principle thereof. For a'detailed description of this forni of my invention, reference may be had to the.

following specification and to the aecompanving drawings forming a part thereof in which:

pass through suitable beerings i3 which carry the yokes 14 which slidablv engage the ribs l5 on the uprights 8. Yl`hetrunnion ll et the right hand side of the platen l0 (Fig. 2) is provided with a projecting shaft l@ on which is iixed a toothed wheel i? adapted to be engaged b v a pawl 18 pivoted on the upper end ot the yoke le. The vokes iii are provided with ears i9 to which inav be attached cords or. cables 20 'for `raising; and lowering 'the platcns l0. rlf'hese cables pass over two wheels or druins 21 to which the inner ends of the cables 2O are fastened, The drums are supported on the "shaft 22 'havinet at one end a sprocket wheel 23 over which passes the sprocket chain rihis sprocket chain also engages a sprocket wheel IiChe crank handle 26 is then turned, thel forms thereby being withdrawn from the solution and the pawl 18 disengaged from the toothedwheel l? to allow the forms to be reversed and placed in an upright pesi tion, as indicated in dotted lines in Fig. The platen l0 and the `orrns thereon are further raised until the pieten closes the bottoni et the casing S. Steam is then admitted through E pipe l2 to the platen 10 and to the inteiior of the terras. vacuum is then produced w` in the casing 8 through the p mter a sufficient aine-unt of evaporaton has taken place from the inateriai on the ornis, the vacuum is discon tinned, the plrfen is again' lowered and ed une i'ne neeessaiv thickness to the article te Jredue however, do not wish to i ted to said sequence of steps, for the saine may be varied as to order or duration, :recording to particular requirement.

means for transferring said support tov dip said forms intosaid material. and for introducing the same into said rvacuum chamber.

2. A dipping and drying apparatus comprising a' chamber adapted to'contain the material of which articles are to be made, a-

vacuum chamber, a supportj upon. which forms for said articles are carried, means carried by said'jsupport forfheating said forms, and means for transferring said support to dip said forms into said material and for introducing the same into said vacuum chamber.

A dipping and drying apparatus comprising a chamber adapted to contain the, material of which articles are to be made,

a vacuum chamber, a platen upon' which of March 1915.

forms for said articles are carried, means carried by said platen for heating said forms, said platen being adapted to close the opening into said vacuum chamber, and

means for transferring said platen to dip said forms into said material and for introduoinvthe same into said vacuum chamber.

4. dippingand drying -apparatus comprising a chamber adapted to contain the material of which articles are to be made, a

vacuum chamber, a hollow platen upon which hollow for-ms for said articles are i carried, a flexible pipe connection connected with said platen, said platen being adapted to close the'opening into said Vacuum chamber, and means for transferring said platen t0 'dip said forms into said material and for introducing the same into said vacuum chamber.l
